VE Gaia

Building climate resilience from the early design stages

VE Gaia: Early Stage Design Analysis

Buildings are responsible for 39% of energy related CO2 emissions. Now, as COP26 brings together world leaders in a collective response to climate change, this is our moment - as building designers, architects and engineers - to play our part. By integrating building performance from the earliest stages of design, alongside creativity and vision, it is possible to significantly reduce the energy and environmental impacts of our buildings to make a real impact.

VE Gaia can help you do just that. That’s why we’re asking you to join us in tackling the climate crisis by taking advantage of our FREE VE Gaia offer for COP26 below. Together we can make a difference.

Free 'Getting Started with VE Gaia' training course

In this online training course, you'll learn how to use the VE Gaia navigator to consider the main aspects of sustainable design for your building: the building shape and form, the construction materials and embodied CO2, carbon emissions, renewable resources, energy, and water use, all within the context of the building location and climate.

Our Commitment to Industry Challenges

RIBA 2030 Challenge

The RIBA 2030 Climate Challenge focuses on four key areas around building design and emissions. 

As users of the IESVE and strong advocates of the RIBA 2030 Climate Challenge, Mesh Energy explain the Challenge and how they use the IESVE to help aspiring projects meet the rigorous targets set out by RIBA.


AIA 2030 Challenge

This new IESVE software integration supports the AIA 2030 Challenge, such that all new buildings, developments, and major renovations shall be carbon-neutral by 2030 by way of sustainable design. Users can now track their progress against the AIA 2030 goals with this streamlined upload.
